The UFO in the middle of Beijing

The opera house in Beijing is a spectacular, future-looking glass palace that clearly demonstrates the aesthetic preferences of the new Chinese architecture: grandeur, illusionism, overwhelming at first sight.

The egg-shaped façade provides a roof for an opera hall, a concert hall and two theatres. The building, designed by the Frenchman Paul Andreu in 2001, was opened on 25 September 2007. The venue for national and international theatre, opera, music and dance performances was built on a total area of 180,000 m². 

The shell-shaped roof with the 6,000 square metre glass façade is about 100 m wide at its base. The glass façade slides between the two titanium-covered façade sections, giving the whole the effect of an opening theatre curtain. The optical impression is enhanced by the surrounding water, which perfectly reflects the façade and leaves a new impression at any time of day.

The visitor enters the building through an underground passage that leads under an artifically created lake. 
The interior functions like a gigantic marketplace: there are streets, plazas, malls, restaurants and parks. In the centre is the opera house, flanked by the concert hall and the theatre.

The new landmark of the Chinese capital, known by Beijing people only as the "egg", is prominently located in the heart of Beijing, just 500 metres from Tian An Men Square and the Forbidden City.

Cofloor” surface heating and cooling also convinces in the Far East

Especially the climatic conditions in Beijing, with cold dry winters with continuous temperatures of -5 °C to the hot humid summers with up to 25 °C, are a challenge for this modern interpretation of building architecture.
The combined Cofloor surface heating and cooling from Oventrop also ensures pleasant room temperatures all year round in this building complex.

As has been proven for a long time in the private sector, surface heating and increasingly also surface cooling are becoming more and more important in complex new buildings as well as in the renovation of a house. The climate comfort, both in heating operation and in alternating operation between heating and cooling, is possible in an energy-saving manner. Compared to radiators, for example, much larger surfaces are used as energy exchange surfaces to temper the room. As a result, the flow temperatures of both the heating and cooling water do not deviate far from the room temperature (in heating mode approximately 35 °C instead of 70 °C flow temperature, in cooling mode this is not below 16 °C).

Therefore, the use of energy-saving heat or cooling generators such as heat pumps with additional cooling function is also possible in an environmentally friendly way. Another energy-saving effect without loss of comfort results from the fact that the normal room temperature can be reduced from the ususal 22 °C to 20 °C.

In addition, surface heating raises less dust than radiators and protects against allergy-causing germs, mites and fungal spores through dry floors.

With the Cofloor system for surface heating and cooling, Oventrop offers the trade not only the first-class valves and fittings, but also all other components for the economical installation of various laying systems.

Oventrop offers a comprehensive, complete range of valves, fittings and controllers for this purpose.
